摘要：
A fully customized digital signal processor for motor field-oriented control is proposed.The instruction set,memory model and interaction method with main-CPU is discussed.Fixing some of the operands in multi-op instructions allows a reduced instruction encoding length and therefore an economical code size.Background execution improves arithmetic and logic unit(ALU) computation parallelism.In this article,the instruction cycles of typical field-oriented control(FOC) algorithm is shown.The silicon implementation of the proposed digital signal processor (DSP) is provided.Taken the commonly used ARM Cortex-M0 processor and several main-stream DSPs as the comparison baseline,the experiment results demonstrate that the micro architecture and circuit implementation of this DSP is energy-efficient and competitive.This approach improves the processing performance at the cost of limited circuit resource. © 2020, Chinese Institute of Electronics.
